In the USA and Canada, concession holders' rights can vary significantly depending on the cemetery's regulations, the province or state, and even local laws. However, some common elements generally apply:

1. Exclusive Right of Burial: Concession holders (also called plot owners) typically have the exclusive right to decide who can be buried in the plot. This right can sometimes be passed on to heirs, though the rules vary.

2. Transfer of Rights: In many places, concession holders may transfer their burial rights to another person, often requiring approval from the cemetery. Some cemeteries restrict this or charge a transfer fee.

3. Interment Regulations: Concession holders may need to follow specific regulations about the type of monuments, headstones, and decorations allowed, as well as rules on grave maintenance.

4. Perpetual or Limited Rights: Some concessions are sold as "perpetual care" (permanent maintenance) plots, while others are sold for limited terms, renewable upon payment of additional fees. In the case of limited-term plots, rights may expire if not renewed.

5. Succession of Rights: In Canada and some U.S. states, cemetery rights can be passed down to heirs. However, rules about inheritance and use of the plot vary by location.
